#106390 - PLAZMA 8.4V 3300MAH NI-MH BATTERY PACK 27.72WH

The HPI Plazma range of battery packs is growing, with several
new options available for hobbyists and racers! This 7-cell pack is
perfect for 2WD buggies, short course trucks and stadium trucks
that can fit it, such as the Blitz and E-Firestorm! You'll
experience more speed and acceleration from the extra voltage, and
more fun as a result!

The Plazma battery range now features a wide range of fantastic
products, including 2 new Ni-MH battery options, including a 7-cell
battery for extra power. We've also got 4 new LiPo hardcase battery
packs, including 2 custom-fit for the Savage Flux monster truck,
and a massive 4S pack that is ideal for vehicles that use 2 battery
packs, such as the Trophy, Vorza and more! Racers have something to
look forward to as well, with the addition of the brand new
PlazmaPro 95C competition line of batteries! We have a normal size
rectangular case 95C battery as well as a saddle pack style battery
for use in kits that require the use of saddle packs.

Note: LiPo batteries must be charged with
a LiPo-compatible charger such as the #101974 - HPI Reactor 500
